采用磁化等离子体的分段线性电流密度卷积时域有限差分(PLCDRC-FDTD)算法研究具有单一缺陷层的一维磁化等离子体光子晶体的缺陷模特性.从频域角度分析得到微分高斯脉冲的透射率,并讨论该光子晶体的缺陷层厚度、位置、周期常数和等离子体参数对其缺陷模的影响.结果表明,改变位置和周期常数不会影响缺陷模的频率,改变缺陷层的厚度可以增加缺陷模数,改变等离子体参数能同时影响缺陷模的频率和峰值.
The defect modes of one-dimensional magnetized plasma photonic crystals with a single defect layer were investigated by using the piecewise linear current density convolution time-domain finite difference (PCDD-FDTD) algorithm of magnetized plasma. The differential Gaussian pulse Transmittance and the influence of defect layer thickness, position, period constant and plasma parameters on the defect mode of the photonic crystal are discussed.The results show that changing the position and the period constant will not affect the frequency of the defect mode and changing the thickness of the defect layer Increasing the defect modulus and changing the plasma parameters can simultaneously affect the frequency and the peak value of the defect mode.
